1. A system for charging an electric vehicle in a facility, the system comprising:
an electric vehicle supply equipment (EVSE) configured to connect the electric vehicle to a power source in the facility, the EVSE being adapted to charge the electric vehicle based at least partially on a control pilot signal;
a current sensor adapted to obtain an input current signal for the power source;
a controller in communication with the EVSE, the controller having a processor and tangible, non-transitory memory on which instructions are recorded for dynamically adjusting the control pilot signal based on the input current signal;
wherein the controller is configured to:
obtain a plurality of factors, including an EVSE circuit breaker rating and a main circuit breaker rating of the facility;
set the control pilot signal to a predefined maximum when the input current signal is less than the main circuit breaker rating of the facility;
set the predefined maximum to correspond to between about 65% and 80% of the EVSE circuit breaker rating; and
reduce the control pilot signal to below the predefined maximum, in at least one of a curved, exponential, and linear fashion, when the input current signal is at or above the main circuit breaker rating of the facility.
